The house was decorated with a decoration deposit of 1 1,000 yuan. Later, when the balcony was closed, the guardrail was removed and it was not refunded. Is this reasonable? I'm already in arrears.

Unreasonable, the deposit is not used for buildings or important pipe fittings or equipment that is not allowed to be installed in the city. This guardrail should not be used. If you don't like the original, you can change it, and you don't have to be more serious with the property. After all, this thing is of great help to safety. If it is not returned to you after replacement or reproduction, you can complain to the local sub-district office or the Housing Authority.
